What is the best video FPS Frame Rate Conversion Filter/Plugin or Software.
My layman's understanding would suggest most software would just repeat a previous frame as required to match your required FPS.
How does a high quality Frame Rate Conversion Software do anything other then create copies of existing Frames?
I have not got a particular format to edit.
Basically looking to increase low fps video x2 or x4.
Is there product available to address problem with intelligently rendered fill frames?
What is the best software product for high quality result.

Not all! Some use motion interpolation.
Motion interpolation does not always work though. FrameRateConverter does very well at using motion interpolation where it works, and frame blending where it is likely to create artifacts.
FrameRateConverter(NewNum=60, NewDen=1, Preset="Fast") ## @ NewNum - The new framerate numerator ## @ NewDen - The new framerate denominator ## @ Presets ## Fast: Basic interpolation ## Normal: Fast + MRecalculate ## Slow: Normal + DCT=4 ## Slower: Slow + calculate diff between DCT=4 and DCT=0 to take the best from both ## Slowest: Slower + use DCT=1 instead of 4
I see .avsi extension is AVISynth plugin.
Excuse my learning as we go, this is all new to me at this stage.
Another question was the smeared or ghost image with movement on webcam recordings.
I read it can occur from parts of separate frames merging?
Not sure that is a good description of problem, but looking for a good plugin to address this in existing videos.
Perhaps a plugin that only acts on areas where the video is moving to preserve good quality frames?

To run FrameRateConverter, you need to understand plugins:
Once you "get" plugins, using FRC is very easy.
You put FrameRateConverter.dll and FrameRateConverter.avsi in the avisynth plugins folder.
Then create a script like this:Code:
DirectShowSource("<some video>") FrameRateConverter(NewNum=60, NewDen=1)
Highly recommended to view your script in VirtualDub (32-bit) to start, because other programs sometimes don't show the error messages when something goes wrong.
Thanks for all the info, helped a lot
The frame rate conversion was a separate subject, horses for courses.
I was reading about deinterlacing and thought it, and low bit rate,
might play a part in smeared image, associated with fast movements of subject and low quality webcam.
I suspect there is not a lot that can be done when the recording quality is bad.
Any plugin suggestions for attempting to improve such quality issues.
What about the order of tasks in AVISynth.
Is there cases where you should put in particular order,
such as Deinterlacing before frame rate conversion?

It's best to start a new thread with a proper subject line so the right people can see it. I wouldn't know about these issues really.
if you want to increase frame rate of interlaced video you deinterlace it first, but there is a special plugin (or group of plugins) called QTGMC that does excellent job to deinterlace 25i/29.97i to 50p or 59.94p which might be what you are looking for, because it basically doubles frame rate. It takes interlaced half frame/fields and makes it a full frame considering vectors of movements. It involves some denoising as well.
That websites describes deinterlacing but it is very old, it does not mention QTGMC (think of it like sophisticated bob basically, described on that page). For SD footage it is almost necesarry today, because contents get blown up on big screens.
If you are dealing with HD interlaced video, yadif bob mode is suitable (avisynth plugin) it is quite alright,it doubles frame rate and it is much, much faster than QTGMC.

is the denoising part of QTGMC settings or separate plugin.
Anything I need to know about denoise settings when deinterlacing.
Lot of de's in this filter stuff.
I downloaded QTGMC with the previous plugins.
The video with issues are done with a webcam, low bite rate/resolution and stability issues.
Should have enough plugins to play around.

yes, but do not expect to restore footage or something, you'd need to try other denoisers to do that, QTGMC is more subtle but there is a certain range to set it up
Not very many webcams record interlaced. I would verify this before you "start off on the wrong foot" or waste time going that route
again, short sample would help you'd be offered what to do
Take folks up on the offer some time down the track.
Also inquired about purchase of Infognition Video Enhancer for AVISynth.
The biggest question is can or should I use any 64bit components in this "Video Kit".
I have downloaded 32bit AVISynth/Plugins and VirtualDub!
My thought being everything should work together,
and there would, presumably be less filter/plugin choices using 64bit components.
What's the experience been for users of 64bit OS?
Can you still manage to find 64bit versions of the Filters discussed in forum?
Or just stick to 32bit Synth and Dub Package?

Vdub can be used on a 64-bit OS. You can install 64-bit too -- they do not interfere with each other.
32-bit AVS must be used with 32-bit Vdub, and 64 with 64.
As for 64-bit filters, there is quite a good selection. Most support high bit depth too BTW.
Or you can use with avisynth http://www.compression.ru/video/frame_rate_conversion/index_en_msu.html
it is old but doesn't mean that is bad. There are some limitation, mentioned on page, like resolution has to be mod16 and video colorspace YV12, what is not big problem.
At least worth to try. It is for 2.5.7 avisynth, hope it is backward compatible.
AviSource("webcam.avi") ConvertToYV12().MSU_FRC(4, "slow")
Or there is also filter for FFMPEG called Minterpolate
But of course, higher input fps, and slower motion means better results.

http://www.compression.ru/video/frame_rate_conversion/index_en_msu.html before getting the dependencies for FrameRateConverter.
Seemed to work ok.
I have not put much time into the study and coding yet.
# v3.33s (mod) 2016 12 06
# - Add TR2=4 and TR2=5
# - add TV_range bool and dither_luma_rebuild (from SMDegrain) Str and Amp
# - for avsplus now QTGMC_Bob is ready for any 420, not only yv12

I took the easy way out and asked, after following hundreds of dead and outdated links to build plugin collection, it was doing my head in.
Found a link to SMDegrain+v.3.1.2d here if anyone needs: http://www.mediafire.com/file/9kd7d6ba2l0m6qd/SMDegrain+v.3.1.2d.zip
Here is the Avisynth Basic Tool Kit, should be enough to experiment with.
Going to leave it for now, feel free to contribute suggestions if you have a favorite.
Thanks for every-bodies input.
